[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-Figure 6 , a multi-angle adjustable bracket for an electrical automation robot arm, comprising:

[0039] A lower plate 1 and an upper plate 2, wherein the upper plate 2 is narrower than the lower plate 1, and the two lower plates 1 are slidably connected to the surface of the lower plate 1 through a plurality of slide plates 13;

[0040] Two lever mechanisms are symmetrically arranged between the lower plate 1 and the upper plate 2. The lever mechanisms include a plurality of rotating rods 801. Four rotating rods 801 form a group, and the four rotating rods 801 are rotatably connected in pairs, and are respectively arranged on the left and right sides of the upper plate 2 and the lower plate 1. The lever mechanisms 8 are used to adjust the distance between the two ends of the lower plate 1 and the upper plate 2 respectively.

[0041] Two second side plates 4 and the first side plate 3 are respectively connected to both ends of the lower plate 1, and the first side plates 3 and the second side plates 4 at upper and lower positions are telescopically connected together through a plurality of support shafts 11;

[0042] A clamping mechanism 6 is connected between the two ends of the two second side plates 4, and the two first side plates 3 are also connected to the clamping mechanism 6, and the clamping mechanism 6 is used to clamp the production materials by bringing the two first side plates 3 closer together and the two second side plates 4 closer together;

[0043] A synchronization mechanism 5 is provided at both ends of the upper plate 2, the synchronization mechanism 5 comprises a transmission 501 fixedly connected to the upper plate 2, and the transmission 501 is connected to the lever mechanism 8;

[0044] A wire winder 10 is installed at both ends of the lower plate 1, and the two ends of the second side plate 4 are rotatably connected to the lower pulley 9, and the two ends of the first side plate 3 are rotatably connected to the upper pulley 7. A wire rope is connected through the wire winder 10, the lower pulley 9, and the upper pulley 7. A hoisting wire mesh 14 is arranged on the wire rope. The two ends of the hoisting wire mesh 14 are fixedly connected to the lower plate 1 and the wire rope respectively. The hoisting wire mesh 14 is used to hoist production materials. The input end of the synchronization mechanism 5 is connected to the lever mechanism 8, and the output end is connected to the wire winder 10;

[0045] The wire winder 10 is provided with two outlets, which are respectively arranged on the two sides of the wire winder 10. The wire rope passes through the two outlets at the same height. The rotating surface of the upper pulley 7 is perpendicular to one of the side surfaces, and the rotating direction of the lower pulley 9 is parallel to the side surface.

[0046] An auxiliary plate 12 is arranged between the first side plate 3 and the second side plate 4 at the vertical position, and telescopic grooves are provided on the auxiliary plate 12 and the first side plate 3, wherein one end of a plurality of support shafts 11 is rotatably connected to the second side plate 4, and the other end is slidably connected to the telescopic groove located below. During use, the support shaft 11 can rotate and one end can slide in the telescopic groove, thereby realizing the telescopic effect, and the amount of production materials clamped and transported can be expanded.

[0047] The lever mechanism 8 also includes a threaded rod 804 that is rotatably connected together. A slide groove 802 is provided on the lower plate 1 for the rotating rod 801 to move. One end of a group of rotating rods 801 is rotatably connected together through a connecting shaft 806. A threaded sleeve 803 is provided on the connecting shaft 806. The threaded rod 804 is threaded through the threaded sleeve 803. The two ends of the upper plate 2 are slidably connected up and down with a torque motor 805 used in conjunction with the threaded rod 804. The driving end of the torque motor 805 is fixedly connected to the threaded rod 804.

[0048] When adjusting the distance between the two ends of the upper plate 2, the torque motor 805 can drive the threaded rod 804 to rotate through the driving end. As the threaded rod 804 rotates, one end of the rotating rod 801 is rotatably installed on the upper plate 2 or the lower plate 1, and the other end is connected together through the connecting shaft 806. The rotating threaded rod 804 can realize the back and forth movement of the threaded sleeve 803 in the relative position, thereby changing the angle between the upper and lower rotating rods 801. The rotating rod 801 of the left group controls the distance between the left ends of the lower plate 1 and the upper plate 2. Similarly, the right side controls the distance at the right end, so that a lever-like structure is formed between the lower plate 1 and the upper plate 2, and the distance between one end decreases and the other end increases. The position angle of the upper plate 2 remains unchanged, and the lower plate 1 will tilt. When the lower plate 1 tilts, it will drive the connected first side plate 3 and the second side plate 4 to tilt. The production materials clamped together are regarded as a square, and the square will deflect with one side of the lower end as the rotation axis.

[0049] The upper part of the torque motor 805 is fixedly connected with a limiting groove 807, which is slidably connected to the upper plate 2. A first spring 808 is provided on the limiting groove 807, one end of the first spring 808 is fixedly connected to the top of the limiting groove 807, and the other end is fixedly connected to the upper plate 2. The limiting groove 807 and the first spring 808 limit and support the movement of the torque motor 805. When the position between the lower plate 1 and the upper plate 2 changes, the torque motor 805 can adaptively adjust the position by moving the limiting groove 807 relative to the upper plate 2.

[0050] The clamping mechanism 6 includes a hydraulic cylinder 601, which is provided with two output pipes. A mounting block 603 is fixedly installed at both ends of the second side plate 4. The mounting block 603 is also fixedly installed on the first side plate 3. A telescopic shaft 602 that matches the output pipe is fixedly installed on the mounting block 603. The telescopic shaft 602 is slidably inserted in the output pipe. The production materials are clamped by the clamping mechanism 6. By hydraulically controlling the hydraulic cylinder 601, the telescopic shaft 602 can be moved through the output pipes at both ends, thereby bringing the two second side plates 4 closer to each other. Similarly, the two first side plates 3 are brought closer to each other to clamp the production materials.

[0051] A camshaft 509 is also fixedly sleeved on the driving end of the torque motor 805, and a fixed groove 502 is fixedly installed at a position below the camshaft 509 on the lower plate 1. An extrusion shaft 503 is installed on the bottom of the fixed groove 502 for sliding up and down through a second spring 513. The camshaft 509 is against the upper end of the extrusion shaft 503. The synchronization mechanism 5 includes a third linkage shaft 507, a first linkage shaft 505, and a second linkage shaft 506. The lower end of the extrusion shaft 503 is rotatably connected to one end of the second linkage shaft 506, and the other end of the first linkage shaft 505 is rotatably connected to the third linkage shaft 507. The third linkage shaft 507 is connected to the input end of the gearbox 501 through an input shaft 508. When the driving end of the torque motor 805 drives the camshaft 509 to rotate, the camshaft 509 contacts the extrusion shaft 503. Since a second spring 513 is arranged under the extrusion shaft 503, the extrusion shaft 503 intermittently moves up and down under the intermittent pressure of the camshaft 509. When the extrusion shaft 503 moves, it will slide back and forth left and right through the second linkage shaft 506, and then the third linkage shaft 507 will move, finally realizing the rotation effect of the input end of the gearbox 501.

[0052] The first linkage shaft 505 is slidably installed on the upper plate 2 through the movable groove 504, the input end of the gearbox 501 is fixedly connected with the input rotating shaft 508, the third linkage shaft 507 is rotatably connected to the end of the input rotating shaft 508, the output end of the gearbox 501 is fixedly connected with the output rotating shaft 512, a reel for winding the steel wire is provided in the steel wire winder 10, the reel extends out of the steel wire winder 10 and is fixedly connected with the linkage reel 511, and a fourth linkage shaft 510 is rotatably connected between the ends on the same side of the output rotating shaft 512 and the linkage reel 511. The input rotating shaft 508 is fixedly arranged, and the third linkage shaft 507, under the pulling action of the first linkage shaft 505, causes the input rotating shaft 508 to rotate with the input end as the center. The output rotating shaft 512 and the linkage reel 511, which are respectively fixedly installed on the output end and the rotating shaft, can realize synchronous rotation under the action of the fourth linkage shaft 510. The frequency required for the rotation of the threaded rod 804 is obviously different from the frequency of releasing the wire rope. The speed difference is adjusted by the gearbox 501, and the mutual linkage is realized through the various components.

[0053] When in use, firstly, the upper plate 2 of the device is directly fixed and installed by a crane, and the crane is operated to directly cover the device on the aligned production materials, the auxiliary plate 12 and the first side plate 3 will be unfolded under the action of their own gravity, and the support shaft 11 will rotate relatively, so that the frame structure formed by the second side plate 4, the auxiliary plate 12, and the first side plate 3 can just cover the production materials, and the crane directly adjusts the upper and lower positions of the lower plate 1 to adapt to the height of the production materials;

[0054] Then, the clamping mechanism 6 is started, and the telescopic shafts 602 connected at both ends are adsorbed under the action of hydraulic pressure. Multiple hydraulic cylinders 601 are started and used together at the same time, so that the two second side plates 4 are close to each other, the two first side plates 3 are close to each other, and the auxiliary plate 12 arranged between the first side plates 3 and the second side plates 4 will also be close to each other accordingly, thereby temporarily clamping the production materials;

[0055] Then, the lever mechanism 8 is started, and one of the torque motors 805 drives the threaded rod 804 to rotate through the driving end. As the threaded rod 804 rotates, the threaded sleeve 803 connected by the thread can move. As the connecting shaft 806 moves, the two rotating rods 801 rotatingly sleeved on its surface will rotate, so that the angles between the two rotating rods 801 are close to each other, and the angle between the rotating rods 801 of the other group remains unchanged, which will eventually cause the relative angle between the lower plate 1 and the upper plate 2 to change. The distance between the lower plate 1 and the upper plate 2 on the first starting side is small, and the horizontal position of the upper plate 2 remains unchanged. The first starting side of the lower plate 1 tilts up, and the change in the horizontal angle of the lower plate 1 will affect the position of the second side plate 4 on the same side. Then, the first side plate 3, the second side plate 4, and the auxiliary plate 12 on the first starting side will all move up and tilt up, which will drive one side of the production material clamped to form a block as a whole to tilt up, and the production material as a whole will tilt with the side of the first side plate 3 that has not moved as the fulcrum;

[0056] While changing the distance between the two ends of the lower plate 1 and the upper plate 2, the driving end of the torque motor 805 will also rotate the camshaft 509. The rotating camshaft 509 intermittently squeezes the extrusion shaft 503 downward, and the extrusion shaft 503 intermittently moves up and down. The extrusion shaft 503 drives the first linkage shaft 505 to move back and forth left and right through the second linkage shaft 506, thereby causing the third linkage shaft 507 to move regularly. The third linkage shaft 507 can realize the rotation of the input shaft 508, which is the input end of the gearbox 501 and the torque The driving end of the power motor 805 rotates at the same frequency. Under the coordination of the gears inside the gearbox 501, the output shaft 512 drives the linkage reel 511 to rotate through the fourth linkage shaft 510, and then the shaft of the wire winder 10 rotates to adapt to the frequency of the hoisting wire mesh 14. The wire rope in the wire winder 10 will be released at the same time. With the release of the wire rope, the hoisting wire mesh 14 installed on its surface will move. One end of the hoisting wire mesh 14 is fixedly connected to the lower plate 1, and the other end is fixedly connected to a certain part of the wire rope.

[0057] First, the first side plate 3 in the start side is moved up and tilted, and the lifting wire mesh 14 can just enter the bottom of the protective rotation from the gap below. At this time, start another torque motor 805, and similarly move the first side plate 3 and the second side plate 4 on the other side up. The torque motor 805 started later operates the wire winder 10 on the other side, and the wire rope will continue to move, and then the lifting wire mesh 14 continues to move forward and finally covers the bottom area of ​​the production materials. The lifting wire mesh 14 supports the bottom of the production materials, and the first side plates 3 and the second side plates 4 on both sides limit the placement of the production materials. The crane directly transports the production materials through the lifting wire mesh 14, and the clamping mechanism 6 can cancel the force on the production materials. Transporting by the lifting wire mesh 14 can achieve long-term and long-distance transportation with less energy consumption. When the production materials need to be unloaded, the lifting wire mesh 14 can be removed from the bottom of the production materials by the reverse operation.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
